camel cxf有效负载模式拦截器抛出组织。阿帕奇。骆驼组成部分cxf。CxfPayload无法转换为javax。xml。使改变

Question

我正在使用同事编写的CXF拦截器将第三方webservice所需的soap头添加到由xsl文件创建的apache camel消息的soap信封中。截击机在我的同事的路线上正常工作，但在我的路线上却失败了。我直接从他的路线复制了我的endpoint，所以我认为这不是问题所在。我问我的同事，他从未见过这样的事情。

我的路线是：

<to uri="bean:applicationName?method=setBodyToBlankXML" />
<to uri="xslt:xsl/applicationName-thirdPartyWebserviceOperationName.xsl" />
<setHeader headerName="operationName">
<constant>OperationName</constant>
</setHeader>
<setHeader headerName="operationNamespace">
<constant>thirdPartyNamespace</constant>
</setHeader>
<to uri="cxf:bean:thirdPartyWebserviceBean" />

他的路线是：

<to uri="bean:applicationName?method=setBodyToBlankXML" />
                        <to uri="xslt:xsl/applicationName-thirdPartyWebserviceOperationName.xsl" />
                        <log message="Display Request ${body}" loggingLevel="INFO" />
                        <to uri="cxf:bean:thirdPartyWebserviceBean" />

在堆栈跟踪中，似乎实际的异常是在CXF本身中引发的。似乎在发生异常时，CXF正在执行任何需要的内部处理，以继续发送请求。

互联网上似乎没有那么多关于这个问题的信息，我唯一得到的信息是邮件列表存档中的一条旧的未回复邮件。我是否做错了什么，这可能是CXF中一个模糊的bug，还是我完全遗漏了其他什么。

Answer 1

我的团队遇到了类似的问题我也看到了那个邮件列表

我们的解决方案是对生产者和消费者使用相同的数据格式。

最初我们使用dataFormat。PAYLOAD at our from（"cxf： bean："）和dataFormat。RAW at our to（"cxf： bean："）。在两个endpoint使用dataFormat。PAYLOAD解决了这个问题。
